A method for generating antireflective coatings for polymeric substrates using a deposition process and/or a dissolving process can provide a coating onto the outer surface of the substrate. Some embodiments can include a GLAD generated fluoropolymer coating or a co-evaporated fluoropolymer coating on a substrate that may achieve ultralow refractive index as well as improved adhesion and durability properties on polymeric substrates. In some embodiments, the deposition process is performed such that a fluoropolymer can be evaporated to form chain fragments of the fluoropolymer. The chain fragments diffused into the substrate can subsequently re-polymerize, interlocking with the polymer chains of the substrate. In some embodiments, the co-evaporation process can form a nanoporous polymer chain scaffold of the fluoropolymer, from which a sacrificial material can be dissolved out. The formed coating can be a multilayer or continuously-graded antireflective coating that has strong adhesion with the substrate.

A thin-film coating applicator assembly is disclosed for coating substrates in outdoor applications. The innovative thin-film coating applicator assembly is adapted to apply performance enhancement coatings on installed photovoltaic panels and glass windows in outdoor environments. The coating applicator is adapted to move along a solar panel or glass pane while applicator mechanisms deposit a uniform layer of liquid coating solution to the substrate's surface. The applicator assembly comprises a conveyance means disposed on a frame. Further disclosed are innovative applicator heads that comprise a deformable sponge-like core surrounded by a microporous layer. The structure, when in contact with a substrate surface, deposits a uniform layer of coating solution over a large surface.

An optical member includes a substrate and a thin film that is disposed on the substrate and contains inorganic particles and a resin. The resin has a volume occupancy of less than 5% in a region up to at least 60 nm in depth from a surface of at least a part of the thin film, the surface being opposite from a substrate-end surface of the thin film.

Provided is a refractive-index-matching thin film, which is an inorganic crystal thin film, wherein a matching layer including inorganic films having different refractive indices is formed on the surface of a substrate and, more particularly, to a refractive-index-matching thin film, which is configured such that a matching layer including one or more inorganic films having different refractive indices is formed on the surface of a substrate made of a polymer, ceramic, metal or combinations thereof, thus protecting the surface of flexible displays such as curved and bendable displays.

A refractive coating such as a white layer is disposed on a housing component of a portable electronic device. The refractive coating includes pigment particles such as titanium dioxide suspended in a carrier medium such as a polymer matrix. The pigment particles each define air pores or other voids formed by at least partially sintering the pigment particles. A difference in refractive index between the air pores and the pigment particles is greater than that between the carrier medium and the pigment particles. Incident light is refracted at interfaces between the pigment particles and the air pores, increasing light refracted by the refractive coating compared to refractive coatings including pigment particles lacking the air pores.

In an aspect, a chromatic facade unit for being attached to a wall (1A) of a building (1) is disclosed that can form a facade (3) of the wall (1A). The chromatic facade unit (11) comprises a support structure (15), a chromatic reflective layer (17) formed on the support structure (15), the chromatic reflective layer (17) comprising reflective layer (43) and a chromatic diffusing layer (41), wherein the chromatic diffusing layer (41) is configured to provide for a specular reflectance that is larger in the red than in the blue and for a diffuse reflectance that is larger in the blue than in the red, and the reflective layer (43) is configured to reflect visible light having passed through the chromatic diffusing layer (41). The chromatic facade unit (11) comprises further an absorbing medium (47) provided in or on the chromatic diffusing layer (41) and/or the reflective layer (43), wherein the absorbing medium (47) is configured to absorb preferred radiation in the infrared spectrum and less in the visible spectrum.

A substrate having inner and outer major surfaces, a plurality of edge surfaces, and a plurality of corner surfaces; and at least one of: (i) a coating applied over a limited area of the outer major surface of the substrate to produce a composite structure, (ii) an intermediate layer applied to the inner major surface of the substrate, and (iii) an elongate discontinuity disposed at one or more corners of the substrate, each of which operates to reduce catastrophic failures in the substrate resulting from a dynamic sharp impact to the outer major surface of the substrate.

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a non-aqueous media utilizing a dispersant having polyisobutylene succinic anhydride structure to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to colour ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and subsequently firing the coloured article is also described.
